Outline of Final Research Achievements

In order to elucidate the whole process of heterotopic ossification (HO) in Fibrodysplasia Ossificans Progressiva (FOP) and to make the sirolimus-based therapy under development more effective, we conducted experiments using FOP patient-derived iPS cells and FOP model mice. As a result, we found that translational regulation, one of the mTOR functions, plays an important role in the pathogenesis of FOP. Furthermore, administration of sirolimus had a preventive effect on recurrence after HO resection, and prophylactic administration can bring about further therapeutic effects.

Academic Significance and Societal Importance of the Research Achievements

本研究課題は基礎生物学的な理解と臨床への応用の両者を対象にした研究である。学術的意義として、FOP疾患における未解決の課題に取り込み、mTORシグナルを介したHO形成過程を解明することは病態の理解を深めるという意味で重要である。社会的意義として、シロリムスの至適な投与段階および再発予防薬としての意義を明らかにすることで、FOP患者の臨床病態の改善に貢献できる研究である。
